title: Theoretical and experimental study of a catadioptric compensator for an aspheric surface.
abstract: A new type of catadioptric compensator is established. The tolerance values of lens spacing, lens thickness, and tilt in mounting are about three times higher than that of the Offner compensator. They overcome the localization of the Offner compensator, improve the test validity, and reduce the test risk of system detection by cross-validation with existing means. The performance of the catadioptric compensator is verified in experiments and theoretically.
